Abstract
A spin valve magnetoresistive head comprises a first spin valve device having a first magnetization free layer and a first magnetization pinning layer via a first non-magnetic intermediate layer, a second spin valve device having a second magnetization free layer and a second magnetization pinning layer via a second non-magnetic intermediate layer, whereby the first and second magnetization pinning layers are magnetized in anti-parallel to each other and the first and second magnetization free layers are magnetized rotatably based on an external magnetic field.
